LISTER-CULTIVATOR.

Specification of Letters Patent.

Patented Nov. 28, 1905.

To all whom it may concern:

Be it known that I, LEWIs E. WATERMAN, a citizen of the United States, residing at Rockford, in the county of WVinnebago and State of Illinois, have invented certain new and useful Improvements in Lister-Cultivators, of which the following is a specification.

The object of this invention is to support the two sets of tools in a manner that they may be moved toward and from each other by a single lever in the construction of the frame supporting the tools and in the various details of construction.

In the accompanying drawings, Figure 1 is a perspective view of my improved two-row lister-cultivator. Fig. 2 is a front elevation of the main frame. Fig. 3 is a. plan view of a pair of carrying-disks.

The main frame comprises the two bars 1 and 2, joined together in the form of a loop, having ends 3 and 4E. The bars are rounded in cross-section. A tongue 5 has a connection with the bar 2 by the bracket 6. A seat-support 7 has a connection with the bars 1 and 2 by means of the bracket 6 and bracket 8. A brace-rod 9 has one end connected to the tongue and its other end connected by a bolt 10 with the seat-support. Brace-rods 11 and 12 connect the ends 3 and 4 of the frame with the tongue. This construction holds the bar 1 vertically over the bar2 and the proper distance apart. Upon the lower rod 2 is mounted two sections of square tubing 13 and 14, one each side of the center. A toothed segment 15 is clamped in connection with the tubing 13 and has its upper end provided with a fork 16, which receives the upper bar 1. This section 13 of tubing supports two bars 17 and 18, connected by a cross-bar 19 in a manner that the bars can be adjusted toward and from each other. A toothed segment 20 is clamped in connection with the tubing 14 and has its upper end provided with a fork 21, which receives the upper bar 1. of tubing supports two bars 22 and 23, connected by a cross-bar 24 in a manner that the bars can be adjusted toward and from each other. Thesebars support shovels 25. Disks 26 are suitably supported by the cross-bars 19.

A connection is formed between the liftinglever 32 and its cross-bar 19 and between the lever 33 and the cross-bar 24. A spring 34 has one end connected to the cross-bar 19 and This section its other end to the lifting-lever 32. A spring 35 forms a connection between the cross-bar 24 and the lifting-lever 33. One end of the frame is supported by the carrying-wheels 36, connected to the tubular section 13, and the other end of the frame is supported by the two disk carrying-wheels 37, connected to the tubular section 14:. The wheels comprising a pair have their forward edges closer together than their rear edges, as shown at Fig. 3.

By means of the hand-levers the bars supporting the shovels and disks can be raised and lowered, and the main frame will be supported by the disks 36 and 37, acting as carryingwheels.

By locating a pair of carrying-wheels so that their front edges are closer together than their rear edges the wheels will better center themselves in the furrow.

A lever 38 is pivoted on the bolt 10, and to the end of the lower section is pivoted a bar 39, the other end of which has a pivotal connection with the forked upper end of the toothed segment 15. A bar 40 has one end pivoted to the lever 38 above its pivotal center and its other end pivotally connected to the fork 21 of the toothed segment 20. By means of this lever both toothed segments 15 and 20 and the parts connected therewith can be moved in the lengthwise direction of the bars 1 and 2 for the purpose of bringing the carrying-disks into the furrows.

By means of the serrated faces the disks can be tipped to give the proper undercut, and by the vertical support for the disks having an axial adjustment the disks can be given more or less land and adjusted to turn earth toward the plants or remove it therefrom.

I claim as my invention 1. In a lister-cultivator, a main frame composed of two bars, one arranged vertically over the other and having end sections, a center brace, a tongue connected to the lower bar, a brace connecting the upper portion of the brace and tongue, and two side braces connecting the end sections with the tongue.

2. In a lister-cultivator, a main frame composed of-two bars, one located over the other, and connected to the tongue by suitable braces, a lever having a pivotal connection with the frame, two sets of tools supported by the frame, and connections between the lever and with the upper bar, a hand-lever for each tools, whereby the tools are moved bodily toquadrant, connections between the hand-leward or from each other. vers and tools, and means for moving the sec- 3. In a lister-cultivator, a frame composed tions of tubing in the lengthwise direction of 5 of two bars, one located over the othber and the rods.,

connected to tie tongue by suitable races, two sections of tubing supported by the lower LEWIS WATERMAN bar, tools supported by each section of tubing, Witnesses: a toothed quadrant supported by each section A. O. BEHEL, IQ of tubing and having a sliding engagement E. BEHEL.
